Plants
Sexual reproduction occurs in many kinds of plants in different ways. Some plants form pollen that fertilizes eggs in the flower or cone, others produce spores.
Angiosperms reproduce using their flower structure:
The petals attract insects and birds to encourage
pollination.
The stigma, style, and ovary make up the
female structure – the pistil. The ovary houses the ovules (eggs) before
and after fertilization
The anther and filament make up the male structure
– the stamen - that produces the pollen.
When the ovary ripens it becomes fruit – that contains the seeds.
Seed
In conifers,
the plant
produces male
and female cones – male cones
contain pollen, while
female cones bear eggs.
In ferns, sexual reproduction takes place by the production of spores that fertilize eggs in
alternating generations of the plant’s life cycle.
Asexual Reproductio
n
Most plants can also reproduce new plants through asexual reproduction – also called
vegetative propagation – where new plants grow from a piece of
the old plant.
Some plants have special structures for vegetative
propagation . . .

Description of Structure
Plants with these Structures
tubers under-ground storage stems,
develop new shoots after dormant
season
potatoes
rhizomes under-ground runners that develop into
new plant
irises
stolens above-ground runners that grow roots of their own then develop into
new plant
strawberries
bulbs underground storage units that
grow into many new plants via division
amaryllis
corms resemble bulbs but with enlarged, solid
stem for food storage
gladiolus, crocus
